Very interesting stuff!! Let me add a joke which came to my mind i read through your article….Mom tells nine year old son arriving for dinner, ” Did you have your bath?”. Reply: “mom, only dirty people take bath!!”

Queen Elizabeth I of England could bathe once a month because of the climate she lived in. If she were living in the tropics, she might have changed her ways!. Bath tubs are OK for cold climates.Hot climates need running water!
